SASH-FASTENER.

Specification of Letters Patent.

Application filed February 14, 1911.

Patented Apr. 4, 1911.

Serial No. 608,499.

To all whom may concern:

Be it known that we, EMANUEL PATE- XAUDE and SAMUEL P. PATENAUDE, citizens of the United States, residing at Korbel, in the county of Humboldt, State of California, have invented a new and useful- Sash-Fastener, of which the following is a specification.

It is the object of the present invention to provide an improved sash fastener arranged to hold the sashes of a window at substantially any desired elevation, which fastener will not be exposed prominently to View from outside the window and may not be reached except from within.

One aim of the present invention is to provide means whereby the fastener may be held inoperative for any desired length of time so as to permit free raising and lowering of the window sashes.

A further aim of the invention is to provide a fastener for this purpose so constructed that it may be placed upon the market and readily applied by anyone to any ordinary window frame with but little alteration of the frame and the sashes.

In the accompanying drawingsFigure 1 is a view in front elevation of a window to which the fastener is applied. Fig. 2 is a view in side elevation of the device mounted upon one stile of the window frame. Fig. 3 is a vertical sectional view on the line 33 looking in the direction indicated by the arrows, in Fig. 2 of the drawings. Fig. is a rear elevation of the device removed from the window frame. Fig. 5 is a vertical sectional view on the line 5-5 of Fig. d looking in the direction indicated by the arrows. Fig. 6 is a detailed perspective view of a portion of one of the window sashes.

in the drawings, the device is illustrated as including, in its structure, a base plate 10. lriounted for rocking movement upon one face of the plate 10 is a shaft 11 and a shaft 12. Springs 13 and 14s are arranged upon these shafts respectively and normally hold them rocked in one direction. Arms 15 and 16 are secured to the shafts 11 and 12 respectively at corresponding ends, the shafts being located one above the other, and these arms, at their upper ends, have pivotal connection as at 17 with finger buttons 18 and 19 respectively. These finger buttons 18 and 19 are slidably mounted through the plate 10 as is clearly shown in Fig. 5 of the drawings and, for a purpose to be presently explained, each of the said buttons is formed in its free extremity with a notch 20.

it will be observed from an inspection of Figs. 4; and 5 of the drawings, that the springs 13 and 1d serve to hold their re spective shafts 11 and 12 normally in a position to project the finger buttons 18 and 19 beyond the outer face of the plate to the maximum degree. It will however be further understood that either of these buttons may be pressed to rock its respective shaft against the tension of the respective spring. At the other end of each shaft 11 and 12, there is fixed an upstanding arm, in the case of the shaft 11, indicated by the numeral 21, and in the case of the shaft 12, indicated by the numeral 22.

Sleeves 23 and 21 are secured upon and project from the rear face of the plate 10 and in their under sides are slotted as at 25. The upper ends of the arms 21 and 22 pro jeot through the slots in the respective sleeves 23 and 24- and engage in seats in the under sides of bolts indicated one by the numeral 26 and the other by the numeral 27. Normally, the shafts 11 and 12 are held by the springs in such position as to project the bolts 26 and 27 beyond the forward face of the plate 10 in the manner illustrated in Figs. 3 and 5 of the drawings.

From the foregoing it will be understood, that by pressing upon the finger button 18, the bolt 26 will be retracted or slid rear wardly in the sleeve 23, and on the other hand, by similarly manipulating the finger button 19, the bolt 27 will be retracted. These bolts 26 and 27 are located in different vertical planes so that one of them will co operate with the lower sash and the other one with the upper sash.

It will be observed from an inspection of Fig. 1 of the drawings that the device above described is applied to one stile of the window frame indicated by the reference character F and by referring to Fig. 6 it will be observed that the corresponding or adjacent stile of each window sash (indicated by the reference character S), is formed with socle ets 28 to receive the projecting ends of the respective bolts 26 and 27. hen so engaged, the bolts hold the respective sashes against up or down movement although such movement of either sash may be accom plished by first pressing against the proper finger button and then moving the sash as desired.

\Vhen the sashes F are completely closed, they will be so held by the bolts 26 and 27 of the device. However, during the day time, it is desirable that the sashes may be freely raised or lowered without the necessitv of manipulating the finger buttons 18 and 19 and, also, where the sashes are very heavy or not properly balanced or where they have become swollen in the frame and are ditlicult to move, it is desirable that the buttons be held depressed or that the device be rendered inoperative in some other suitable manner. Preferably, this is accomplished by the provisiol'i of detents engage able one with each of the buttons when the same are in position to render the respective bolts inoperative. Each of these detents consists of an arm 29 which is mounted for rocking movement upon a face plate 30 through which the buttons .18 and 15) project. Each arm has a laterally projecting end portion 31 which is adapted to be engaged in the notch 20 in the respective button.

Whatis claimed is:

1. A device of the class described comprising a base plate, a rock shaft upon the plate, arms projecting from the shaft at the ends thereof, a spring upon the shaft between the arms normally holding the shaft rocked in one direction, a finger button connected with one arm and projecting through the plate and operable to rock the shaft against the tension of the spring, a sliding bolt also projecting through the plate and actuated by movement of the other arm, and a keeper for the bolt.

2. A device of the class described comprising a base plate, a slotted sleeve projecting from one face of the base plate, a rock shaft upon the plate, arms projecting from the shaft at the ends thereof, one of the said arms projecting through the slot in the sleeve, a spring upon the shaft between the arms normally holding the shaft rocked in one direction, a finger button connected with the other arm and operable to rock the shaft against the tension of the spring, a sliding bolt engaged by the first mentioned arm and movable in the sleeve to project beyond the plate when the shaft is rocked against the tension of the spring, and a keeper for the bolt.

3. A device of the class described comprising a base plate, a rock shaft upon the plate. arms projectil'ig from the shaf'. at the ends thereof, a spring upon the shaft between the arms normally holding the shaft rocked in one direction, a sliding bolt operativelv cugaged by one arm and projecting through the plate, a keeper for the bolt. a linger button connected with the other arm and operable to rock the shaft against the tension of the spring, and a detent for the linger button.

4. A device of the class described comprising a base plate, av rock shaftupon the plaic. arms projecting from the shaft at the ends thereof, a spring upon the shaft between the arms normally holding the shaft rocked n one direction, a sliding bolt opcrativelv eugaged by one arm and projecting through the plate, a keeper for the bolt. a linger button connected with the other arm and operable to rock the shaft against the tension of the spring, and a detent for the finger button. the said detent comprising a rocking arm having a laterally projecting portion arranged to engage in a notch in the end of finger button.

In testimony that we claim the foregoing as our own, we have hereto ailixed our signatures in the presence of two Witnesses.
